Abstract
BACKGROUND The purpose of this study was to determine the safety and efficacy of enteral nutrition in combination with microbial preparations for bowel preparation in elderly patients with colorectal cancer. MATERIAL AND METHODS Were divided 160 patients diagnosed with colorectal cancer into a control group (n=80) and an experimental group (n=80) by random number table method. The control group took the traditional intestinal preparation, and the experimental group took oral enteral nutrition combined with microbial preparations. Both groups were treated by the same medical team. The postoperative recovery, complications, nutritional status, inflammation, and other indicators of the 2 groups were compared. RESULTS The nutritional status of the experimental group was significantly better than that of the control group, the incidence of tissue inflammation and postoperative complications was significantly lower than that of the control group, and the stool test results of patients with postoperative diarrhea were better than those of the control group, and the difference between groups was statistically significant. CONCLUSIONS The intestinal preparation using enteral nutrition combined with microbial preparations can alleviate the systemic inflammatory response in elderly patients, improve the nutritional status, reduce the occurrence of postoperative complications, and facilitate rapid postoperative recovery.

Abstract
Elderly people are particularly vulnerable to COVID-19, with a high risk of developing severe disease and a reduced immune response to the COVID-19 vaccine. A randomized, placebo-controlled, double-blind trial to assess the effect of the consumption of the probiotic Loigolactobacillus coryniformis K8 CECT 5711 on the immune response generated by the COVID-19 vaccine in an elderly population was performed. Two hundred nursing home residents >60 yrs that had not COVID-19 were randomized to receive L. coryniformis K8 or a placebo daily for 3 months. All volunteers received a complete vaccination schedule of a mRNA vaccine, starting the intervention ten days after the first dose. Specific IgG and IgA antibody levels were analyzed 56 days after the end of the immunization process. No differences between the groups were observed in the antibody levels. During the intervention, 19 subjects had COVID-19 (11 receiving K8 vs. 8 receiving placebo, p = 0.457). Subgroup analysis in these patients showed that levels of IgG were significantly higher in those receiving K8 compared to placebo (p = 0.038). Among subjects >85 yrs that did not get COVID-19, administration of K8 tended to increase the IgA levels (p = 0.082). The administration of K8 may enhance the specific immune response against COVID-19 and may improve the COVID-19 vaccine-specific responses in elderly populations.

Abstract
PURPOSE OF REVIEW Biological age is the concept of using biophysiological measures to more accurately determine an individual's age-related risk of adverse outcomes. Grading of the degree of frailty and measuring biomarkers are distinct methods of measuring biological age. This review compares these strategies for estimating biological age for clinical purposes. RECENT FINDINGS The degree of frailty predicts susceptibility to adverse outcomes independently of chronological age. The utility of this approach has been demonstrated across a range of clinical contexts. Biomarkers from various levels of the biological aging process are improving in accuracy, with the potential to identify aberrant aging trajectories before the onset of clinically manifest frailty. Grading of frailty is a demonstrably, clinically, and research-relevant proxy estimate of biological age. Emerging biomarkers can supplement this approach by identifying accelerated aging before it is clinically apparent. Some biomarkers may even offer a means by which interventions to reduce the rate of aging can be developed.

Abstract
There is a lack of knowledge about malnutrition and risk of malnutrition upon admission and after discharge in older medical patients. This study aimed to describe prevalence, risk factors, and screening tools for malnutrition in older medical patients. In a prospective observational study, malnutrition was evaluated in 128 older medical patients (≥65 years) using the Nutritional Risk Screening 2002 (NRS-2002), the Mini Nutritional Assessment-Short Form (MNA-SF) and the Eating Validation Scheme (EVS). The European Society of Clinical Nutrition (ESPEN) diagnostic criteria from 2015 were applied for diagnosis. Agreement between the screening tools was evaluated by kappa statistics. Risk factors for malnutrition included polypharmacy, dysphagia, depression, low functional capacity, eating-related problems and lowered cognitive function. Malnutrition or risk of malnutrition were prevalent at baseline (59-98%) and follow-up (30-88%). The baseline, follow-up and transitional agreements ranged from slight to moderate. NRS-2002 and MNA-SF yielded the highest agreement (kappa: 0.31 (95% Confidence Interval (CI) 0.18-0.44) to 0.57 (95%CI 0.42-0.72)). Prevalence of risk factors ranged from 17-68%. Applying ESPEN 2015 diagnostic criteria, 15% had malnutrition at baseline and 13% at follow-up. In conclusion, malnutrition, risk of malnutrition and risk factors hereof are prevalent in older medical patients. MNA-SF and NRS-2002 showed the highest agreement at baseline, follow-up, and transitionally.

Abstract
BACKGROUND & AIMS The world's over-65 population is expanding rapidly, and the risk of malnutrition is prevalent in this population. Meeting nutritional needs is a recognized strategy to reduce and address multiple debilitating adverse health outcomes associated with malnutrition. The objective of this randomized, controlled trial was to determine the effects of oral nutritional supplement (ONS) containing beta-hydroxy-beta-methylbutyrate (HMB), along with dietary counseling, on health outcomes in community-dwelling older adults at risk of malnutrition. METHODS Strengthening Health In ELDerly through nutrition (SHIELD) studied adults aged ≥ 65 years in Singapore who were recruited between August 2017 and March 2019. Participants were community ambulant and classified as medium or high risk for malnutrition using Malnutrition Universal Screening Tool (MUST). Participants (n = 811) were randomly assigned to one of two study treatments for 180 days: (i) two servings/day of ONS containing HMB with dietary counseling (n = 405) or (ii) two servings/day of placebo supplement with dietary counseling (n = 406). The primary composite outcome was 'survival without hospital (re)admission and with at least 5% weight gain to day 180'. Dietary intakes, nutritional and functional outcomes were measured at baseline, 30, 90, and 180 days. RESULTS A higher proportion in intervention group met the 180-day primary composite outcome compared to placebo (33.4% vs. 8.7%, P < 0.001), largely driven by body weight component (36.2% vs. 9.4%, P < 0.001). Survival and hospital (re)admission rate were not significantly different between the groups. Weight, BMI, and mid upper arm circumference were significantly greater in the intervention group compared to placebo during the study (all P < 0.001), and at days 30, 90, and 180 (all P < 0.05). The odds of having better nutritional status during the study were also significantly higher in the intervention group compared to placebo, as measured using MUST risk (OR = 2.68, P < 0.001) and vitamin D status (OR = 4.23, P < 0.001). Intervention group had significantly higher energy, protein, fat, and carbohydrate intakes than the placebo group (all P ≤ 0.017). Leg strength at day 90 was significantly greater for the intervention group than for the placebo group (LSM ± SE: 12.85 ± 0.22 vs. 12.17 ± 0.22; P = 0.030). Handgrip strength for females was significantly higher at day 180 for the intervention group compared to placebo (LSM ± SE: 14.18 ± 0.17 vs. 13.70 ± 0.17; P = 0.048). Within the low appendicular skeletal muscle mass index (ASMI) subgroup, the intervention group had significantly greater calf circumference at days 90 and 180 compared to placebo (both P ≤ 0.0289). CONCLUSIONS For community-dwelling older adults at risk of malnutrition, daily consumption of specialized ONS containing HMB and vitamin D for six months, along with dietary counseling, significantly improved nutritional and functional outcomes compared to placebo supplement with dietary counseling.

Abstract
BACKGROUND & AIMS Poor nutritional status leads to multiple adverse outcomes, but few studies have assessed its role as a risk factor for incident frailty and death in community-dwelling older adults. Hence, the aim of this paper is to assess the role of nutritional status using the Global Leadership Initiative on Malnutrition (GLIM) criteria in the risk of frailty and mortality in Spanish community-dwelling older adults. METHODS We used data from two waves (waves 2 (2011-2013) and 3 (2015-2017)) from the Toledo Study of Healthy Ageing, which is an observational, prospective cohort (average follow-up = 3.18 years) of 1660 older (≥65 years) adults living in the community. Nutritional status categories were defined according to the GLIM criteria, which uses a two-step approach. First, screening for malnutrition risk. Once positive, individuals were classified as malnourished according to some phenotypic (body mass index, grip strength and unintentional weight loss) and etiologic (disease burden/inflammation and reduced food intake or assimilation) criteria. Frailty was assessed using both the Frailty Index (FI) and Frailty Trait Scale (FTS). Mortality data was obtained through the National Death Index. RESULTS From the 1660 older adults, 248 participants (14.04%) were classified as 'at malnutrition risk' (AMR) and 209 (12.59%) as malnourished (MN). AMR and MN subjects were older and with worse functional status (frailer). Adjusted cross-sectional analysis showed an association between nutritional status and frailty by both FI and FTS. Adjusted longitudinal analyses showed that AMR was associated with higher risk of frailty, using both the FTS (OR: 1.262; 95% CI: 1.078-1.815) and the FI (OR: 1.116; 95% CI: 1.098-1.686), while being malnourished was associated with higher mortality risk (OR: 1.748; 95% CI: 1.073-2.849), but not with incident frailty at follow-up period. CONCLUSIONS Nutritional status, assessed through GLIM, predicts in a dose-dependent manner the risk of frailty and death. Being at malnutrition risk predicts the risk of becoming frail at follow-up period, whereas being malnourished predicts mortality. These findings highlight the importance of assessing the nutritional status of community-dwelling older adults to identify the ones at risk of developing frailty or death and inform targeted nutrition-focused interventions.

Nutrients. 2021;(9)
Abstract
At hospital discharge, many older patients are at health and nutritional risk, indicating a requirement for ongoing care. We aim to evaluate the effects of comprehensive individualized care by geriatric-experienced care professionals, the so-called "pathfinders", on nutritional status (NS) of older patients after discharge. A total of 244 patients (median age 81.0 years) without major cognitive impairment were randomized to Intervention Group (IG: 123) or Control Group (CG: 121) for a 12-month intervention, with up to 7 home visits and 11 phone calls. The comprehensive individualized care contained nutritional advice, when required. The intervention effect after three (T3m) and 12 (T12m) months on change in MNA-SF (Mini Nutritional Assessment-Short Form) and BMI was evaluated by Univariate General Linear Model (ANOVA), adjusted for age, sex, living situation, and activities of daily living. At baseline, mean MNA-SF did not differ between IG and CG (10.7 ± 2.6 vs. 11.2 ± 2.5, p = 0.148); however, mean BMI was significantly lower in IG compared to CG (27.2 ± 4.7 vs. 28.8 ± 4.8 kg/m2, p = 0.012). At T3m, mean change did not differ significantly between the groups, neither in MNA-SF (0.6; 95%CI: -0.1-1.3 vs. 0.4; -0.3-1.1, p = 0.708) nor in BMI (-0.2; -0.6-0.1 vs. 0.0; -0.4-0.4 kg/m2, p = 0.290). At T12m, mean change of MNA-SF was significantly higher in IG than in CG (1.4; 0.5-2.3 vs. 0.0; -0.9-0.8; p = 0.012). BMI remained unchanged in IG, whereas it slightly declined in CG (0.0; -0.7-0.6 vs. -0.9; -1.6--0.2 kg/m2, p = 0.034). We observed rather small effects of comprehensive individualized care by pathfinders on NS in older patients 12 months after discharge. For more pronounced effects nutrition expertise might be needed.

Abstract
INTRODUCTION Optimizing the approach to older adults with cancer is now a priority given the increasing frequency of new cancer diagnoses that are made in the older population. The comprehensive geriatric assessment (CGA) represents the gold-standard for (1) defining prognosis and ability to withstand cancer treatments, (2) exploring the multiple aspects that define the complexity of frail older persons, and (3) designing person-tailored interventions. MATERIALS AND METHODS In this document, based on a comprehensive revision of the literature, the Italian Society for Geriatrics and Gerontology proposes a CGA model (ONCOGER CGA) to be adopted by oncology centers for their routine approach to older patients with cancer. RESULTS AND DISCUSSION A widespread use of this standardized CGA format will facilitate comparisons across institutions, promote studies based on a multidimensional patient assessment, and foster the inclusion of geriatric endpoints in oncological clinical trials. Furthermore, we predict that the use of a standardized CGA approach will increase the integration of geriatricians into oncology care teams with the final result of improving therapeutic choices and clinical outcomes.

Abstract
Almost two in three patients who are aged 75 years and older and scheduled for surgery for colorectal cancer (CRC) are undernourished. Despite evidence that perioperative nutritional management can improve patients outcomes, international guidelines are still insufficiently applied in current practice. In this stepped-wedge cluster-randomized study of five surgical hospitals, we included 147 patients aged 70 years or older with scheduled abdominal surgery for CRC between October 2013 and December 2016. In the intervention condition, an outreach team comprising a geriatrician and a dietician visited patients and staff in surgical wards to assist with the correct application of guidelines. Evaluation, diagnosis, and prescription (according to nutritional status) were considered appropriate and strictly consistent with guidelines in 39.2% of patients in the intervention group compared to only 1.4% in the control group (p = 0.0002). Prescription of oral nutritional supplements during the perioperative period was significantly improved (41.9% vs. 4.1%; p < 0.0001). However, there were no benefits of the intervention on surgical complications or adverse events. A possible benefit of hospital stay reduction will need to be confirmed in further studies. This study highlights the importance of the implementation of quality improvement interventions into current practice for the perioperative nutritional management of older patients with CRC.

Abstract
BACKGROUND & AIM: Increased intestinal permeability (IP) can occur in older people and contribute to the activation of the immune system and inflammation. Dietary interventions may represent a potential strategy to reduce IP. In this regard, specific food bioactives such as polyphenols have been proposed as potential IP modulator due to their ability to affect several critical targets and pathways that control IP. The trial aimed to test the hypothesis that a polyphenol-rich dietary pattern can decrease serum zonulin levels, an IP surrogate marker involved in tight junction modulation, and can beneficially alter the intestinal microbiota, and IP-associated biochemical and clinical markers in older subjects. METHODS A randomised, controlled, cross-over intervention trial was performed. Sixty-six subjects (aged ≥ 60 y) with increased IP based on serum zonulin levels, were randomly allocated to one of the two arms of the intervention consisting of a control diet (C-diet) vs. a polyphenol-rich diet (PR-diet). Each intervention was 8-week long and separated by an 8-week wash out period. At the beginning and at the end of each intervention period, serum samples were collected for the quantification of zonulin and other biological markers. Faecal samples were also collected to investigate the intestinal microbial ecosystem. In addition, anthropometrical/physical/biochemical parameters and food intake were evaluated. RESULTS Fifty-one subjects successfully completed the intervention and a high compliance to the dietary protocols was demonstrated. Overall, polyphenol intake significantly increased from a mean of 812 mg/day in the C diet to 1391 mg/day in the PR-diet. Two-way analysis of variance showed a significant effect of treatment (p = 0.008) and treatment × time interaction (p = 0.025) on serum zonulin levels, which decreased after the 8-week PR-diet. In addition, a treatment × time interaction was observed showing a reduction of diastolic blood pressure (p = 0.028) following the PR-diet, which was strongest in those not using antihypertensive drugs. A decrease in both diastolic (p = 0.043) and systolic blood pressure (p = 0.042) was observed in women. Interestingly, a significant increase in fibre-fermenting and butyrate-producing bacteria such as the family Ruminococcaceae and members of the genus Faecalibacterium was observed following the PR intervention. The efficacy of this dietary intervention was greater in subjects with higher serum zonulin at baseline, who showed more pronounced alterations in the markers under study. Furthermore, zonulin reduction was also stronger among subjects with higher body mass index and with insulin resistance at baseline, thus demonstrating the close interplay between IP and metabolic features. CONCLUSIONS These data show, for the first time, that a PR-diet can reduce serum zonulin levels, an indirect marker of IP. In addition, PR-diet reduced blood pressure and increased fibre-fermenting and butyrate-producing bacteria. These findings may represent an initial breakthrough for further intervention studies evaluating possible dietary treatments for the management of IP, inflammation and gut function in different target populations.
